GS8A019090FAT

GS8A019090FAT Description

The GS8A019090FAT from TT Electronics/IRC is a high-performance 8-resistor network in a 16-pin narrow SOIC package, designed for precision applications requiring stable resistance values. Built with thin-film technology on a ceramic substrate, it offers excellent thermal stability and low noise. Each resistor features a 909Ω ±1% tolerance with a tight ±0.05% ratio tolerance, ensuring consistent performance in differential circuits. The isolated design (ISOL) allows independent resistor operation, making it ideal for signal conditioning and voltage division. With a ±100ppm/°C temperature coefficient, it maintains reliability across a -70°C to +125°C operating range. The 0.1W power rating per resistor (0.8W total) and 100V maximum voltage rating suit demanding environments.

GS8A019090FAT Features

• Ceramic SOIC package (9.91mm x 5.99mm x 1.45mm) with gull-wing leads for robust surface-mount assembly.
• Thin-film technology delivers low TCR (±100ppm/°C) and high accuracy (±1% absolute, ±0.05% ratio).
• Isolated resistor network (8 independent 909Ω elements) for flexible circuit design.
• Wide temperature range (-70°C to +125°C derated) and 100V max rating for industrial use.
• Non-automotive (PPAP: No) but suitable for precision analog, medical, and test equipment.
• Non-RoHS compliant; ideal for legacy or high-reliability systems where lead-free isn’t required.

GS8A019090FAT Applications

• Precision voltage dividers in instrumentation and sensor interfaces.
• Signal isolation in data acquisition systems and ADC/DAC circuits.
• Impedance matching for RF and communication modules.
• Medical devices requiring stable resistance under thermal stress.
• Industrial control systems where derated power handling (up to 125°C) is critical.

Conclusion of GS8A019090FAT

The GS8A019090FAT excels in applications demanding high accuracy, thermal stability, and isolation. Its ceramic SOIC construction and thin-film resistors provide superior performance over polymer-based networks, particularly in harsh environments. While not RoHS-compliant, it remains a top choice for legacy or specialized designs. Engineers will value its tight tolerances, low TCR, and robust packaging for critical analog circuits.
